The headline is about exposing your IP, which frankly isn't that big of a deal. The actual article says it exposed your IP, and then includes arbitrary code execution as the after thought... Clearly the code execution is the massive vulnerability here lol
If only leaking your IP was the huge exploit lmao. It literally allowed for arbitrary code execution which is infinitely worse. Honestly bad title by the author of that article, it's far more serious than they let on.
Pretty unfortunate bug but at least they patched it pretty quickly it seems.
If you're worried about your IP being "leaked" you have no idea what an IP is. You can literally grab everyone's IP using the console commands to list the players.
No, most multiplayer games and services these days only share your IP with the server, and not with other players.
Leaking your IP to someone malicious can mean DDoS attacks and rough geolocation. IP can be a good narrowing to find your address when combined with additional information.
SC2 is not a game one would expect to leak your IP and is a valid, small concern.
Status no longer reports user Ips as those are hidden through some steam routing, I'm not sure if rcon status still reports it but that would be limited to server admins. If you open the steam overlay while in CS it shows some of the details.
